[0026] Please refer to Figures 1-4 , the present invention provides a technical solution: an assembly structure of an electrical thermal protector, including a first thermal protector mounting cover 1, a thermal protector mounting seat 7 is fixedly connected inside the first thermal protector mounting cover 1, a current thermal protector 8 is fixedly installed on the thermal protector mounting seat 7, a limiting component, the limiting component is arranged on the thermal protector mounting seat 7, the limiting component includes a limiting plate 12, the limiting plate 12 is fixedly connected to the current thermal protector 8, the limiting plate 12 is in an "L" shape, a movable plate 11 is slidably connected inside the thermal protector mounting seat 7, the movable plate 11 is clamped with the limiting plate 12, a fixed rod 13 is fixedly connected to the surface of the thermal protector mounting seat 7, the movable plate 11 is slidably connected to the fixed rod 13, and a spring 14 is sleeved on the surface of the fixed rod 13.

[0027] There are two limiting components, which are symmetrically arranged on the left and right sides of the thermal protector mounting seat 7 respectively.

[0028] Four sliders 10 are fixedly connected to the surface of the current thermal protector 8, and four sliding grooves 9 are formed on the surface of the thermal protector mounting seat 7. The four sliders 10 are respectively slidably connected to the corresponding sliding grooves 9.

[0029] The second thermal protector mounting cover 2 is arranged on the first thermal protector mounting cover 1. Four first connecting columns 5 are fixedly connected to the inner wall of the first thermal protector mounting cover 1. Four second connecting columns 6 are fixedly connected to the inner wall of the second thermal protector mounting cover 2. The four second connecting columns 6 are respectively slidably connected to the corresponding first connecting columns 5. A bolt 4 is arranged inside the first connecting column 5 and the second connecting column 6. The first thermal protector mounting cover 1 and the second thermal protector mounting cover 2 are fixedly connected by the bolt 4.

[0030] Two wire passing grooves 3 are formed on the surfaces of both the first thermal protector mounting cover 1 and the second thermal protector mounting cover 2.

[0031] When using this device, first pass the wire of the equipment through the wire passing groove 3 and electrically connect it to the current thermal protector 8, which is convenient for thermal protection of the electrical equipment through the current thermal protector 8. After the current thermal protector 8 has been used for a period of time, the electrical components inside it may age, resulting in a decrease in its sensitivity. In order to ensure the normal operation and safety of the equipment, it is necessary to regularly check and replace these aging components. At this time, it is also necessary to disassemble the current thermal protector 8. During the disassembly process, first use tools to disassemble the bolt 4, and separate the second thermal protector mounting cover 2 from the first thermal protector mounting cover 1. Expose the current thermal protector 8, disassemble the wire connected to the current thermal protector 8, and then squeeze the movable plate 11 towards the current thermal protector 8. The movable plate 11 squeezes the spring 14. The movable plate 11 slides on the surface of the fixed rod 13, so that the second limiting block 16 contacts the thermal protector mounting seat 7, and the movable plate 11 is separated from the limiting plate 12.

[0032] Pull out the current thermal protector 8 upward to separate the current thermal protector 8 from the thermal protector mounting seat 7. The current thermal protector 8 drives the slider 10 to slide inside the sliding groove 9, which is convenient for disassembling the current thermal protector 8 and replacing the aging components inside the current thermal protector 8.

[0033] After the aging components inside the current thermal protector 8 are replaced, the installation process of the current thermal protector 8 is opposite to the disassembly process. The limiting plate 12 is limited by the movable plate 11, and the slider 10 is limited by the chute 9, which is convenient for fixing the current thermal protector 8 and preventing the current thermal protector 8 from shifting during use, thus improving the stability of the current thermal protector 8 during operation.

[0034] Furthermore, the limiting plate 12 is limited by the movable plate 11, which is convenient for fixing the current thermal protector 8. When the current thermal protector 8 needs to be maintained or replaced, the disassembly process is also simple and fast, facilitating disassembly and repair, improving the repair efficiency, reducing production losses caused by equipment downtime, increasing the production efficiency of the equipment, and improving the stability of the equipment operation.

[0035] By using the chute 9 and the slider 10, it is convenient to limit the current thermal protector 8. The limiting design can ensure the stable position of the current thermal protector 8 in the equipment, and it will not affect its normal operation due to vibration or movement, preventing the current thermal protector 8 from accidentally falling off or being damaged during equipment operation, improving the overall safety and reliability of the equipment, reducing the mechanical stress and thermal stress on the current thermal protector 8 in the equipment, and thus extending its service life.

[0036] Working principle: When using this device, first pass the wire of the equipment through the wire groove 3 and electrically connect it to the current thermal protector 8, which is convenient for thermal protection of the electrical equipment through the current thermal protector 8. After the current thermal protector 8 is used for a period of time, the electrical components inside it may age, resulting in a decrease in its sensitivity. To ensure the normal operation and safety of the equipment, these aging components need to be regularly inspected and replaced. At this time, the current thermal protector 8 also needs to be disassembled. During the disassembly process, first use tools to remove the bolts 4, and separate the second thermal protector 2 from the first thermal protector mounting cover 1. Expose the current thermal protector 8, remove the wire connected to the current thermal protector 8, then squeeze the movable plate 11 towards the current thermal protector 8. The movable plate 11 squeezes the spring 14, and the movable plate 11 slides on the surface of the fixed rod 13, so that the second limiting block 16 contacts the thermal protector mounting seat 7, and the movable plate 11 is separated from the limiting plate 12.

[0037] Pull out the current thermal protector 8 upward to separate the current thermal protector 8 from the thermal protector mounting seat 7. The current thermal protector 8 drives the slider 10 to slide inside the chute 9, which is convenient for disassembling the current thermal protector 8 and replacing the aging components inside the current thermal protector 8.

[0038] After the replacement of the aging components inside the current thermal protector 8 is completed, the installation process of the current thermal protector 8 is opposite to the disassembly process. The limiting plate 12 is limited by the movable plate 11, and the slider 10 is limited by the chute 9, which is convenient for fixing the current thermal protector 8 and preventing the current thermal protector 8 from shifting during the use of the current thermal protector 8, thereby improving the stability of the current thermal protector 8 during operation.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
